PDBsumstructure summary

TheBCL2 associated agonist of cell death[5] (BAD)protein is apro-apoptotic member of theBcl-2 gene family which is involved in initiatingapoptosis. BAD is a member of theBH3-only family,[6] a subfamily of theBcl-2 family. It does not contain aC-terminal transmembranedomain for outermitochondrial membrane andnuclear envelope targeting, unlike most other members of theBcl-2 family.[7] After activation, it is able to form aheterodimer with anti-apoptotic proteins and prevent them from stopping apoptosis.

Mechanism of action

[edit]

Bax/Bak are believed to initiate apoptosis by forming a pore in the mitochondrial outer membrane that allowscytochrome c to escape into the cytoplasm and activate the pro-apoptotic caspase cascade. The anti-apoptoticBcl-2 andBcl-xL proteins inhibit cytochrome c release through the mitochondrial pore and also inhibit activation of the cytoplasmic caspase cascade by cytochrome c.[8]

Dephosphorylated BAD forms a heterodimer withBcl-2 andBcl-xL, inactivating them and thus allowingBax/Bak-triggered apoptosis. When BAD is phosphorylated byAkt/protein kinase B (triggered by PIP3), it forms the BAD-(14-3-3) protein heterodimer. This leavesBcl-2 free to inhibitBax-triggered apoptosis.[9] BAD phosphorylation is thus anti-apoptotic, and BAD dephosphorylation (e.g., by Ca2+-stimulatedCalcineurin) is pro-apoptotic. The latter may be involved in neural diseases such as schizophrenia.[10]
